When you first purchased your laptop did you plug in your adapter to give your battery a full charge? If not then try a new battery when buying something like that always charge at least 12 hours before play.

Laptop failure


hi


never leave a system running unattended for long period of time without a battery back up (UPS), as low and high current spikes will cause damage to the circuitry of the computers mainboard.

Have you tried using the AC adapter to power up the computer ? if that works and the battery is dead, simply replace the battery. if the system is not powering up at all, then the issue is bad AC adapter or the mainboard is damaged from overload of current.

Tip

Troubleshooting Laptop Power Failures - The Battery


Symptom:

Battery does not charge while the laptop is plugged.


Diagnosis & Solution:

First thing is to make sure that there is AC power to the adapter. Some AC adapters have an indicator LED which glows when they are receiveing power from wall outlets. If your AC adapter does not have one, then make sure that the cord from the wall outlet to the AC adapter is firmly plugged into the AC adapter. Also make sure that the AC adapter is plugged into an operational wall outlet. You could also check the laptop's power indicator LED to verify whether it is receiving AC power from the wall outlet or not.

Next thing is to make sure that the AC adapter's connector tip is fully plugged into the power receptacle in the laptop. If this did not help, then the next step is to check & confirm that the AC adapter itself or the cable connecting it to the laptop has not failed. You can easily verify this by using a digital multimeter set to measure DC voltage. Use the digital multimeter's probes to measure the output voltage from the connector at the end of the adapter's cord to the laptop. Compare the reading you get to the nominal DC voltage required by the laptop, which you could find written on a label stick to the bottom of the laptop. The output DC voltage from the AC adapter should not read significantly less than the nominal DC voltage required by the laptop. If you find no or a significantly low output DC voltage from the AC adapter, then you will have to replace this AC adapter with a new one.

It is also necessary to make sure your AC adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the AC adapter. Voltages should be the same, or the AC adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the AC adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the AC adapter will be providing insufficient amperes to charge the battery. Of course, the AC adapter's nominal amperage might be OK, but it degraded on usage. You can verify this by using a good or new AC adapter, or by testing your laptop's AC adapter with another laptop.

If the previous tests confirmed that everything is OK so far but your laptop's battery is still not charging when the laptop is plugged, then there might be a possibility that the battery is not making good contact with the laptop's charging circuitry. To eliminate this possibility as a root cause of the battery not charging, turn off and unplug the laptop, take the battery off the laptop, and using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self. When done, put the battery back into the laptop, plug it, and turn it on. Check if the battery starts charging or not.

What if after all this the battery is still not charging? Well, we might then start to suspect that the battery itself is bad. This could be verified either by testing the battery in a similar laptop, or by swapping the battery with a new one or one which is known to be in a good working condition. If your battery does not charge when tested in the other laptop, then it is obvious that the battery is bad and has to be replaced. However, if your battery starts charging in the other laptop, then we are left with a couple possibilities: your laptop needs a BIOS update, or your laptop's charging circuitry is defective.

When laptop owners call tech support to report that their battery isn't charging or the life doesn't seem to be what it should, tech support will often tell them to download the latest BIOS. While it's marginally possible that the laptop shipped with a BIOS that has been improved in regards to battery management, the BIOS upgrade process, called flashing, is not reversible without special equipment. In other words, if something goes wrong, instead of having a laptop with a battery charging problem you'll have a collection of perfectly good laptop parts that won't do anything. Flashing the BIOS is a last resort we only recommend if you find references on the Internet that it fixed an identical charging problem for somebody else with your exact model.

If at last it turns out to be a defective charging circuitry, then you will definitely need to disassemble your laptop in order to gain access to its motherboard. The motherboard should then be checked for any burnt out components in the area surrounding the power receptacle. Burnt out components will need to be replaced, or if not possible, the motherboard will have to be replaced.

My Fujitsu Lifebook AH530 says 'Plugged in, Not Charging'. Battery problems!? Its a new laptop that has worked less than 40 hours. And not quite clear about the functionality of the "Full" button...


Hey there my i have an answer for your question if you think that plugged in but not charging means anything related with the software is all rubbish, i had a brilliant answer just try few simple steps,
1) Try to change different wall outlet
2) Shut down your computer and disconnect the battery and also the Ac adapter which is connected to your laptop, and then once your computer is Off just press and hold power button for at least 15-20 sec and yes do not lift your finger from the power button
3) Reconnect everything Battery as well as your Ac adapter, and try to see if the issue is resolved or not
4) Just download latest BIOS update from your computer manufacture website , Flash BIOS and check if the issue is resolved or not
5) If everything fails just try and check if the Ac adapter pin is burnt or not, you will see a black spot or something like a burnt spot on the Ac adapter pin of your laptop, if you see this just take any pointed device like Knife etc just scratch clean the black spot and once the black spot is properly cleaned then just connect the pin to the wall outlet and t see the Magic

Hey guys if you really think this works just post you comments or likes so that i will feel happy , really this things works on my 1 year old Fujitsu laptop and i have also worked for
companies like HP and Dell.

Fujitsu esprimo mobile only charges when it is on


Hi,
No that not normal.
Turn the laptop off and remove the AC power and then the battery. Plug in AC power only and start the laptop, let it boot into the operating system and then turn it back off.
Remove AC power and reinsert the battery, then plug in AC power again and look for the charge indicator LED light on the front of the laptop.
If the light comes on then it's charging.
If it doesn't then there is a problem with the laptop.
I would recommend giving Fujitsu a call as their customer service is excellent.

Good luck.

you need do check:
1) no charging means adapter input problem, first check your adapter DC output voltage is ok
2) check DC jack socket on the motherboard:
--- DC socket any pin disconnected, you need use iron and flux to fix it
--- DC socket damage(broken),you have to change it
3) if DC socket connection normall, the DC/DC circiute near around DC socket some component damage, you need find a technacian to repair.
hope help you to deal it well
